1. The problem statement, all variables and given/known data The figure shows the force Fx exerted on a particle that moves along the x-axis. Draw a graph of the particle's potential energy as a function of position x from 0m to 1.1m. Let U be zero at x=0m. 2. Relevant equations W = F*d U = mgh 3. The attempt at a solution I'm pretty confused about how to start this problem. How do you know what equation to use in this situation? My best idea is to use W = F*d because it includes both Force and Displacement, and relates them with Work, which is equal to the change in Energy of the system. However, I don't know how to use this to find the Potential Energy at a given Position. Please help!
